I'm making a google sign in process in my app.
Whenever I open my app it crashes and gives NoClassDefFoundError
I checked the logcat and found this:-

Why this error is occurring? Please help me!
I found the problem while debugging.
The problem was in andoidx.appcompat class not found
In app build.gradle, I changed this line of dependencies:
implementation 'androidx.appcompat:appcompat:1.4.1'
To:
implementation 'androidx.appcompat:appcompat:1.3.1'
Maybe the newer version has changed the classpath.
